Notes[]

^This list consists of British royal family members entitled (in the earliest cases retroactively) to the styles of His or Her Royal Highness or His or Her Majesty, as defined by Letters Patent in 1864,[1] 1898,[2] 1917,[3] 1996,[4] and 2012.[5] According to the aforementioned Letters Patent, British royal family members entitled to the style of Royal Highness are the children and male-line grandchildren of the British monarch and previous British monarchs,[1][3] the children of the eldest son of the Prince of Wales,[2][5] and all their current or widowed spouses.[4] This list also includes those male-line descendants of British monarchs who, prior to 1917, were entitled to the "style and attribute" of His or Her Highness with the designation of a "Prince (or Princess) of the United Kingdom of Great Britain and Ireland."[6]

^ abAs this is a list of British royal family members, individuals are listed by their British royal title by birth, grant, or by marriage.

^ abTo maintain consistency within the table, the dates of birth and death are given in the New Style.

^Letters Patent on 20 November 1947 entitled then Lieutenant Sir Philip Mountbatten to "hold and enjoy the title, style and attribute of Royal Highness."[21] Letters Patent on 22 February 1957 gave then Philip, Duke of Edinburgh, "the style and titular dignity of a Prince of the United Kingdom of Great Britain and Northern Ireland."[22]

^On 23 April 1799, Prince Ernest Augustus was granted the "Names, Styles, and Titles of Duke of Cumberland, and of Teviotdale, in the Kingdom of Great Britain, and of Earl of Armagh, in the Kingdom of Ireland."[74]

The generations indicate descent from George I, who formalised the use of the titles prince and princess for members of the British royal family. Where a princess may have been or is descended from George I more than once, her most senior descent, by which she bore or bears her title, is used.
